Abstract
The study of transition metal based materials displaying colossal magnetoresistance (CMR) is one of today's most exciting fields of research mainly due to the scientific challenge of finding the possibly common root (if that exists) of the CMR effect in the various materials. In this review we present novel results obtained by 57Fe Mössbauer studies done on three different types of CMR materials, namely the cobalt based perovskites La0.8Sr0.2FexCo1-x, O3-d, the Sr2FeMoO6 double perovskite, and copper containing chalcogenide spinels (Fe1-xCuxCr2S4).
